Once an eye is extended by 1-week intervals, if recurrent exudative disease is detected again, the treatment interval for the next visit is reduced by 1 week, compared to the previous treatment interval, and will continue to be decreased by 1-week intervals until dry or the 4-week interval is reached. Once a dry macula is again established, the most recent interval between treatments is maintained for one additional visit; if the macula remains dry at this time, the interval will then be extended by 1-week increments.
